Dear Sebastian,
<div class=""><br class="">
</div>
<div class="">Fieldtrip only compares apples with apples, oranges with oranges, same-named electrodes with one another, and indeed also same frequency bins (and time points).</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">In your case your well-motivated intention is to ask Fieldtrip to compare alpha band in sub-001 with alpha band in sub-002 etc. This is perfectly fine, but would require you to fool around a bit with the subject-specific data structures. I’d extract
per subject the alpha frequency specific data, resulting in a data structure with just a single frequency bin (and possibly multiple time bins). Next, you’d need to replace the individual data structures’ ‘freq’-bin with a value that is common across subjects,
say 10. Then, it should be business as usual.</div>

<div class="">Best wishes,</div>

Dear FieldTrip community,
<div class=""><br class="">
</div>
<div class="">Is it possible to run cluster-based permutation tests (<i class="">ft_freqstatistics</i>) with individual frequency bands?</div>
<div class=""><br class="">
</div>
<div class="">I have an EEG experiment in which I want to compare alpha ERD/ERS between two conditions. I also have resting state recordings of the participants from which I extracted the peak alpha frequency to calculate individual frequency band ranges for
each participant (like suggested by Klimesch and practiced in many papers).</div>
<div class=""><br class="">
</div>
<div class="">How would I only include those frequencies that fall into each participant’s alpha band? As far as I understand it, the
<i class="">cfg.frequency</i> argument of <i class="">ft_freqstatistics</i> only allows the specification of a fixed band.</div>
<div class=""><br class="">
</div>
<div class="">Any help would be greatly appreciated!</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>
<div class="">Sebastian</div>
